With the AS-i gateways from Bihl+Wiedemann you can transmit digital and analog data which have been read remotely through AS-i slaves to the host controller and set the output signals from the host controller to the actuators over the respective bus system. [more]

In addition to the gateways with fieldbus and Ethernet interfaces as well as devices with USB ports, Bihl+Wiedemann also offers solutions with all the common hard- and software interfaces for PC-assisted automation. [more]

Active Distributors AS-i from Bihl+Wiedemann allow you to make any sensor or actuator AS-Interface capable. Even modules without their own AS-i terminal can be easily integrated into an existing AS-i network using these active distributors.[more]

Circuit board modules enable sensor and actuator OEMs the possibility of making their modules AS-i capable with the help of a fully engineered and certified AS-i slave board which can be simply and easily integrated into the respective device. [more]

Bihl+Wiedemann offers a range of control and signal devices based on an innovative enclosures. The basic line is available from stock. On request it is also possible to equip the enclosure with one or two locations with any of the common control and signal devices. [more]

AS-i makes full use of all its strengths in material handling technology. The motor modules from Bihl+Wiedemann allow 24V motors to be controlled directly through AS-i without the need for an additional control device. [more]

Bihl+Wiedemann offers the right module for accessing any safety input signal. Both control cabinet modules (IP20) and field modules (IP67) are available. From a single safety input or output to safety multi-I/O modules we offer the right AS-i slave for your requirements. [more]

Active distributors AS-i Safety from Bihl+Wiedemann allow you to make any safety sensor, safety push-button or switch AS-Interface capable. Even modules without their own AS-i terminal can be easily integrated into an existing AS-i network using these active distributors AS-i Safety. [more]

Thanks to the wealth of our experience with gateways and bus couplers you will find at Bihl+Wiedemann a variety of “special solutions” for various coupling requirements. Our Master simulators not only make it possible to test the gateway functionality of our AS-i Masters. [more]

The Right Protocol for any Controller

One of the Easiest Installation Concepts Worldwide

With conventional parallel wiring, at least four lines per E-STOP are necessary to achieve PLe, plus additional two lines for the lighting. In case of other safety sensors even more lines might be needed.

Bihl+Wiedemann devices, on the other hand, can send up to 62 safe signals plus the supply voltage over just one 2-conductor cable.

Relieves the Fieldbus

PLC independent safety technology relieves the higher level controller: instead of many individual fieldbus slaves only the Safety Gateway is connected to the fieldbus. It collects the safe sensors and actuators directly in the field and controls the actuators.

The use of Bihl+Wiedemann devices enables compact machinery design, since for example the space for decentralized control cabinet can be saved. Therefore the wiring effort required for doors with interlocks for example is significantly reduced. The piercing technology greatly reduces time and effort compared with expensive and cumbersome connector assembly. 

The field installation concept is always the same and reduces the fieldbus slaves – greater overview

Free Selection of Sensors and Actuators

If for example multiple light barriers from manufacturer X are used for optoelectronic protective devices in combination with safety doors with interlocks from manufacturer Y, conventional installation requires that all the components be wired in the control cabinet.

With the active distributors from Bihl+Wiedemann all sensors and actuators can be easily integrated into the network regardless of manufacturer:

Safety switches

Safety sensors

Guard doors

Optoelectronic protective devices

The active distributors from Bihl+Wiedemann allow sensors and actuators to be connected in the field directly where they are used. Such flexible use offers many advantages from the construction site to the continuous flow production.
